British Prime Minister Keir Starmer will hope to win agreement from President Emmanuel Macron on tougher measures to control migration on Thursday, the final day of a three-day trip when the French leader was lavished with pomp and ceremony.

After being welcomed by King Charles, who sat next to Macron in a carriage procession to Windsor Castle on Tuesday, Starmer will want to see something concrete to back up Macron¡¯s promise of greater ¡°cooperation and tangible results¡± on migration.

Starmer, whose popularity has slumped since he won an election landslide last year, needs a win on bringing down high levels of immigration, particularly the number of asylum seekers arriving in small boats, to try to curtail the rise of Britain¡¯s populist Reform U.K. party, led by Brexit veteran Nigel Farage.
